My CCB payments have suddenly stopped

If JET has finished and has not been cancelled, by uploading the non-authorised Jet Hours to CCMS it will block payment of the CCB.
Cancel Attendances for all the weeks that have been uploaded since JET finished. Remove JET from the Data Entry screen, Re-submit Attendances.
A few days later (because refreshed JET/CCB data needs to be verified in the Centrelink system) Download Payments from CCMS– Display Payments Already Downloaded (will display multiple weeks) – Update Accounts.
